How we picked these
"When I moved from Sydney to Perth four years ago, I was surprised to find out I couldn't actually compare electricity providers. Synergy is the only supplier of electricity servicing Perth, so that decision was made for me. When it comes to gas, however, I was able to compare and choose. I naturally gravitated towards AGL for gas as I had been with them previously and liked that they offered a monthly billing option. We use very little gas in our house, and our bill works out to about $30 per month."
Compare electricity suppliers in Perth and WA
Due to the way energy is regulated in Western Australia, most residents aren't able to choose their electricity retailer. Synergy services Perth and parts of the south-east region while Horizon Power operates in the rest of the state.
However, you might be able to choose from 1 of 3 basic tariff types available:
- Single rate tariff. Pay a daily supply charge and then for the power you use - set at one price per kWh. This means no matter what time of the day you use electricity, it all costs the same. (Synergy and Horizon)
- Time of use tariff. Pay a daily supply charge and then a different price per kWh for your usage at peak, off-peak and super-off peak times throughout the day. (Synergy only)
- Combined tariff. Available for those who live and run a business from the one address. Pay a daily supply charge and then for your usage at stepped rates. That means you pay a different amount per the number of units of electricity you use. (Synergy and Horizon)
There's also some notable exceptions.
Did you know?
What electricity plan options do I have in Perth and WA?
In the southeast of the state, you'll be serviced by Synergy.
You can choose between 3 tariff types, 2 of which are residential-only:
- Home Plan (A1) tariff. Single rate tariff.
- Midday Saver tariff. Time of use tariff.
- Home Business Plan (K1) tariff. Combined/stepped usage tariff for customers running a business from home.
In regional WA your electricity provider is Horizon Power. You can choose between the following 3 plans:
- Residential (A2) tariff. Single rate tariff.
- Combined Use (K2) tariff. Combined/stepped usage tariff.
- Prepaid Power. This plan lets you pay for your energy costs upfront and share costs with other householders.
Do you have to use Synergy for electricity in Perth?
If you live in Perth or the wider South West Interconnected System (SWIS), Synergy supplies your electricity. Outside the SWIS, your retailer is Horizon Power. Either way, WA residential customers can't choose their electricity retailer.
This is because the state isn't connected to the national energy market.
Instead, Western Australia is a unique market that has its own electricity market, with its own regulations and 2 networks. These are broken down into the South West Interconnected System (SWIS) covering Albany to Kalgoorlie and a second network which is anything outside of the SWIS network.
These are further broken down into a number of regions including:
- Kimberley region
- Pilbara region
- Gascoyne and Mid West region
- Goldfields-Esperance region
Residential customers on both networks are supplied by a single retailer, but there is one notable exception for large businesses.
If you're a large enough business you will be able to negotiate with various suppliers.
This is based off two criteria:
- Spending more than $15,000 per year on electricity
- Use more than 50,000 kWhs
This is due to counting as contestable customers, which are available to negotiate with various providers.
